The present invention relates to e bedp'em cleaner and sterilizer and air ob ect'r of the invention is to provlde a construction having a; bed pan support whieh occupiese position 'where the bedpanqnay be fitted thereto when' the cover is opened ai1d-which itlltO matically moves to discharge the contents of the bed pan with the elosingofthecontainer. Another" object ofthe invention is to provide a construction in" which provi- Sll11lS' 111E1CliG for supplying Water or steam over the entire inner surfaces of the bed pan.

Another object of the iilveiition is to pro-' Y pamtu's being open and in the position it 00'- cupies when receiving a'be'd path;

A bed; pair support" is provided which is moVable'to positioii whereit my readily receive the-bed pa n withoutspilling the contents, and which is movable to a position where "the entire contents may be discharged into; the combined sterilizer and wash-irig container 1. This support comprises" prefe'r ably a rock shaft 17", iirtliis'iiistence; in the form of a tube which isjou'rnalled'atopposite'ends in the opposite sides ofthe 'steri lizer andwashing container 1. This tuhe projects from both sides of the chamber and has one endelosedjby a" plug 18, its oppo siteend being ro'tz'itiibly connected to asuit ablejfiuidsupply as will be hereinafter set forth." The" tube 17' has a T coupling 19 therein which conneets WVith a hollow sup port 20 011" which the bottom of the bed an 21may rest. 7 In orderto hold the'bed pan on this'support, retaining arms areprovided. In this instan'c'egi-foiir of'sueh arir'is 'a'r e pro The arms 22 which are-nearest therearipor; ti'onof the support wheii the latter is-in' the position" shown? in Fig! 1 are closer together thah'the hooked armssothat the bed pail which is'ui'srro'we at its'dischargeend may be readily plec'e'd or; theshppdrtQO with the discharge'end toward the "rear of the recep- Which may te'cle 1. All of the l ariiis a're preferebly in the tom of tubes or nozzles; thearn'i's 22 be? mg deflected one towardFthe" other dotvh: ar-my and away from the disehatg'e of-the bed pair? ahdthe arms" 23 being deflected one tower d 'the other do'whwerdlyjtoweid the diselmrge' portibn .ofthejbed pi'n As a Any suitable means may be employed for moving the bed pan support from its upper receiving position to its lower discharge position. In this instance, the hollow rock shaft 17 has two arms 24 rigidly secured to opposite ends thereof and pivotally connected at 25 totwo links 26 which in turn are pivoted at 27 to opposite sides of the cover 9. It is apparent that, with this arrangement, when the cover 9 is opened, the bed pan support will be swung upwardly to an inclined receiving position as illustrated in Fig. 1, and, when the cover 9 is closed, the bed pan support will be swung downwardly to a discharging position, as shown in Fig. 2.

Provision is made for delivering flushing water to the apparatus. This flushing water is received by way of a supply pipe 28 which leads to a hand pressure valve 29 that connects by a piping 30 with a discharge opening 31 arranged above the bed pan support when the latter is in its lower position. This bed pan support delivers a large stream of water over the exterior of the bed pan while the latter is in inverted position, completely flooding all exterior parts thereof. The piping 28 also connects with a piping 32 with a handvalve 33 connecting with a coupling member 34: in which the hollow shaft 17 turns and to which it has a connection which permits water from the piping 32 to pass to the hollow rock shaft 17 and from the latter to the arms 22 and 23, so that the interior of the receptacle may be flushed at will when the latter is in its lowered position. It is desirable also to flush the walls of the receptacle 1 with the opening of the cover 9 and to this end the rock shaft 10 of the cover has a cam 35 which cooperates with a plunger 36 of a valve 37 in a piping 38 which leads to a spray nozzle 39 delivering a wide fiat stream in immediate proximity to the interior face of the receptacle 1, the valve being opened when the cam 35 moves off the plunger 36 and closed with the depression of the plunger.

In the use of the invention, the container being opened as shown in Fig. 1, a bed pan is placed on the support 20 and the cover is lowered. With the lowering of the cover the bed pan assumes its position as shown in Fig. 2 and discharges its contents. At the same time, the valve 37 is closed. Then the valve 33 is manually operated to discharge water through the nozzles 22 and 23 into the bed pan. thus effectively washing the interior of the latter. After the interior is washed, the valve 29 is operated to draw a large stream through the opening 37 on the exterior of the receptacle, whereby both the interior and the exterior of the bed pan are thoroughly flushed. After this flushing, the bed pan is sterilized, this being effected through a steam supply 40.which connects with the manually operated valve 41 in turn connecting with the couplings 3 f so as to supply steam by way of the coupling 34 to the nozzle arms 22 and 23. This steam not only plays directly on the interior of the bed pan but the entire container 1 becomes charged with steam so that an effective sterilization of the pan is secured. WVith the opening of the cover, the interior of the container is flushed by the nozzle 39. The steam and odors pass out of the container through a vent 12 at the rear of the container leading to any suitable vent pipe.

It is apparent that the invention may also be employed for cleaning and sterilizing urinal receptacles, a hooked nozzle 22 being inserted in such receptacle and serving to hold the latter thereon during cleaning and sterilizing.

hat I claim as my invention and desire to secure by Letters Patent is:

1. The combination with a receiving container and a movable cover therefor, of a support, for a bed pan or the like having means for detachably holding a bed pan and movable about a fixed axis on the container from an upper receiving position to a lower discharging position, and mechanism for opening and closing the cover having connection with the movable support for moving the latter to a receiving position when the cover is open and for moving it to a discharging position when the cover is closed.

2. The combination with a receiving container and a hinged cover therefor, of a swinging support for a bed pan or the like, an arm connected to said support and arranged on the exterior of the container, and a link pivoted to said arm and to said cover so as to cause the support to move to receiving position when the cover is moved to open position and to move the support to discharging position when the cover is moved to closed position.

3. The combination with a receiving container, of a movable support for a bed pan or the like pivotally mounted in the container, nozzles carried by said support for discharging into said bed pan or the like and means for supplying a fluid to said nozzles..

4-. The combination with a receiving container, of a rock shaft mounted in the container having a passageway therethrough connected with a suitable fluid supply, and a support for bed pans or the like mounted on said rock shaft and provided with nozzles communicating with said rock shaft for discharging into the bed panor the like. 5. The combination with a receiving container, of a movable hollow support for a bed pan or the like arranged within the container and having hollow arms communicating with said support for engaging a bed pan or the like, said arms being provided with nozzle-s discharging into said bed pan or the like, and means for supplying the fluid to said support from the exterior of 5 the container.

6. The combination with a receiving container, of a hollow rock shaft connecting with a suitable fluid supply, a hollow support for a bed pan or the like connected with said rock shaft and communicating therewith, and hollow arms communicating with said hollow support and having nozzles for discharging into the bed pan or the like.
